Bellroy just updated its phone cases for the iPhone 7 and just like the previous designs they feature their signature card slot in a slim and streamlined case. What's really interesting is that the back panel not only has a slot for an additional SIM card, but they've also managed to fit in a slot for a SIM tray ejection tool. 

Which is incredibly useful when you land at your destination and can't seem to find the proper tool to switch SIM cards. And if you've ever been hit with crazy data fees when traveling then you know exactly how valuable this little feature can be.
